PATENT LEE STURGES, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE CHICAGO STAMP-ING COMPANY, OF SAME PLACE.

METALLIC VESSEL.

SPECIFICATION forming part of Letters Patent No. 458,352, dated August25, 1891.

Application tiled March 19, 1891. Serial No. 385,624. (No model.)

To all whom it may concern.-

Bc it known that I, LEE STURGES, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveInvented certain new and useful Improvements in Metallic Vessels, ofwhich the following is a specification.

The present invention is applicable generally to all Vessels which havea main part, such as a body or cover and an auxiliary part, such as aknob, a handle, an ear, a spout, or the like attached thereto; and theobject of said invention is to enable the formation of a tight jointbetween said parts without the use of solder.

To this end the invention consists in certain features of novelty thatare particularly pointed out in the claims hereinafter.

In the accompanying drawings, which are made a part of thisspecification, the invention is shown applied to the ears of a pail,Figures l to 5, inclusive, to the handle ot' a dipper, Fig. G, and tothe spout of a pot, Fig. 7.

Fig. l is a vertical section of a portion of a pail and of the ear whencompletely attached thereto. Figs. 2 to 5, inclusive, are sections ofthe parts at four different stages during the process of attaching them.Fig. 6 is a section of a portion of a clipper andof a portion of thehandle attached thereto. Fig` 7 is a section of a portion of a pot andof the spout attached thereto. Fig. 8 is a diagrammatic view showing theresult of the various steps of the process upon the attached orauxiliary part.

A represents the main part, say the body, of a vessel, having an openinga, andB represents the attached or auxiliary part having an externalannular groove 11,01? U -shaped cross-section, which receives the metalforming the margin of the opening a. The part B has also an internalannular groove of U- shaped cross-section b', which receives the marginof a disk or diaphragm C, which may be either imperforated orreticulated accorciing to the nature and purpose of the part B. If saidpart loe the ear for the attachment of a bail D, as shown in Figs. l to5, inclusive,

or the handle of a dipper or other vessel, as

shown in Fig. 6, or the like, the diaphragm is impert'orated and thejoint around its margin is made water-tight. If, however, said part bethe discharge-spoutot the vessel or the like, then the diaphragm isreticulated and serves as a strainer. In either case the method ofsecuring the parts together is the same and is best illustrated by Figs.2 to 5, inclusive. The part B is formed with a sh oulder b2 and anannular flange b3, as shown in Figs. 2 and 3. The diaphragm C is placedupon the shoulder b2, as shown in Fig. 3, and the flange b3 contractedso as to bear upon the periphery of the diaphragm and so as to form theannular groove ZJ for receiving the margin of said diaphragm, as shownin Fig. 4. Unless the diaphragm be reticulated this makes the part Bwater-tight, and it then only remains to secure it water tight to themain part A. This is done by inserting the contracted flange, Fig. 4,through the opening a., as shown in Fig. 5, and expanding it, causing itto completely till the opening and embrace the metal forming the marginthereof, as shown in Figs. l, 6, and 7. cessive steps result in formingin the part B the two U -shaped grooves, as shown in Fig. S.

In practice thepart removed from themain part A in forming the opening ais used for the disk or diaphragm C when a water-tight joint is desired.

-For the sake of clear-ness the drawings show all the parts vofexaggerated thickness.

Having thus described my invention, the following is what I claim as newtherein and desire to secure by Letters Patent:

l. In a metallic vessel, the combination, with the part A, havingopening a, ofthe part B, having external annular groove b, in which themetal forming the margin of the opening a fits, and the diaphragm C,situated within the part B, substantially as set forth.

2. In a metallic vessel, the combination, with part A, having opening a,of part B, hav-V .ing external annular groove b, in which the metalforming the margin of the opening a fits water-tight and having aninternal annu- These suc-v lar groove b, and the diaphragm C, havingannular groove b', andthe imperforate diaios margin confined Within thegroove b,sub phragm C, having its margin tted Water- 1o stantially asset forth. tight in the groove b', substantially as set 3.
